Study Notes
Objectives
- Define perfusion as the blood flow through arteries and capillaries that delivers nutrients and oxygen while removing cellular waste.
- Identify modifiable risk factors for perfusion issues: elevated serum lipids, hypertension, tobacco use, physical inactivity, obesity, diabetes, metabolic syndrome, psychological states, and high stress.
- Recognize signs and symptoms of perfusion disturbances: dyspnea, cough, fatigue, cyanosis, pallor, and edema.
- Consider personal and family cardiac history impacting patient treatment including conditions like hypertension, congenital heart disease, and history of sudden death.
Assessment Components
- Evaluate cognition, vital signs, heart sounds, apical pulse, peripheral pulses, and subjective data through health interviews.
- Inspect and palpate for jugular venous distension (JVD) as a marker of fluid volume status.
Heart Sounds
- Auscultation techniques: use bell for low-pitched sounds and diaphragm for high-pitched sounds.
- Normal heart sounds: S1 and S2; may also hear extra sounds (S3, S4), dysrhythmias, and murmurs.
Inspection & Palpation
- Locate apical impulse (point of maximal impulse) at the 4th-5th intercostal space along the midclavicular line.
- Observe for carotid bruits which indicate narrowed blood vessels.
Pulses
- Assess pulse characteristics: rate, regularity, and quality ranging from 0 (absent) to 4 (bounding).
- Perform capillary refill test by blanching nail beds; normal time for color return is 1-2 seconds.
Edema Types
- Pitting Edema: leaves an indentation upon applying pressure.
- Brawny Edema: chronic with discoloration, no pitting, remains swollen despite treatment.
Doppler Assessment
- Use a Doppler ultrasound to detect weak peripheral pulses and measure low blood pressure, enhancing the ability to hear pulsatile sounds.
Device Utilization
- TED Hose: Thromboembolic devices used for promoting venous return via external pressure.
- SCDs (Sequential Compression Devices): alternately inflate and deflate to reduce venous stasis.
Laboratory Studies
- B-Type Natriuretic Peptide (BNP): neurohormone indicating heart failure when elevated (normal < 100 pg/mL).
- Prothrombin Time (PT) normal range: 11.0-13.0 seconds.
- International Normalized Ratio (INR) is a key lab value for assessing coagulation.
